• In this article we discuss the need for metal strip flatness and the state of the art for its measurement, which is of top importance for the metal processing industry. There is a strong pressure for quality that demands on-line measurement that is robust to the perturbations introduced by further processing down the line. We sketch the design of an innovative on-line metal strip flatness measurement device based on the recovery of depth information from two parallel laser projected lines. Preliminary results show its robustness on simulated and real data.
